+12V to system master switch input. If Master switch is not used connect between
battery +12V to the outgoing DC line to valve/s.
Independent fuse per valve: Connect between master switch +12 V output to each
outgoing +12V supply line to valve.
Barrel or butt crimp-on splicing connectors are recommended to connect the wire
Other connection methods may be used as long as connection is solid and secure.
Fuse holder is meant to be installed in a protected but accessible area or
compartment, not exposed to water. If water exposure is expected and
inevitable use a waterproof IP 66 rated holder available from most auto stores.
